an improved 'railway track tamping machine for use in tamping I" between the ties of railroads and in making the roadbed, the object of the invention being to provide an improved machine of this character which is mounted on a car adapted to travel on the track and is provided with a suitable motor and with means for automatically tamping between the ties and making the roadbed, the invention consisting in. the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings :-Figure 1 is ay side elevation of a tamping machine constructed in accordance with my invention. showing the same arranged on a track and in operf tive condition. Fi cal transverse sectional view of the same, on the plane indicated by the line a--a of Fig. 1. Fig. 3 is a vertical central sectional view of the saine. Fig. t is a vertical. transverse sectional view of the same on the plane indicated by 'the line 6?) of Fig. 1.

For the purposes of my invention, l. provide a suitablcvcar or platform 9 which has wheels 2 for operation on the rails 3 of a railroad track. The car also carries a suitable motor which is here indicated. as an electric motor t adapted to receive current from a trolley Wire 5 and providedv with a suitable .conductor 6 for this purpose. The motor ishere shown as mounted on a suitable stand 7 and is provided with aA driving pulley 8. I- also provide a frame 1 which is here shown as rectangular' in form and is arranged transversely on and depends from the under side-'of the car or platform 1 and is fixed thereto. A vertical standard 10 which is rectargular in cross section is mounted for vertical movement in an opening in the upper side'of the frame 9 at the center of said frame, and the said standard is provided at its'upper end witha shaft 11 on which are an operating pulley 12 and an idler pulley 123. A power belt 14 driven by the pulley 8 of the motor and may be engaged either 'fith the puiley 1% or the. polu 2 a vertiley 13 b a suitable Shipper or belt shifter 15 Whic may be of the construction here shown or any other suitable construction.

A screw shaft 16, which is vertical, has its upper end secured to the lower end ojr' the vertically movable standard 10 which carries Spammen of Letters Patent rarement/rar. ai, iota. application inea any 22, 191s. sensi no. 780,552.

the pulleys 12-13, the said screw being far#` ranged in the center of the frame 9 and pass:

b e in f ing through and' being vertically Inova Unthreaded openings in a pair of spaced cross bars 17-18 with which the said frame 9 is provided. A traveling nut 19. is arranged between the said cross bars, engages the screw 16 and is formed with a crown gear 20, which is horizontally arranged and the teeth of Which'are engaged by a pinion 21 on the inner end of a shaft shaft being mounted in bearings 23 with which the frame 9 is rovided and being provided at its outer end) with a hand crank 24 whereby it may be readily turned in order to cause .the traveling nut 19 to be revolved and the said nut coacting with the screw 16 to raise or lower the standard 10, as may be desired.

Spaced from opposite sides of the frame 9 and equ'idistant therefrom are a pair of rock shafts 25 which are mounted inf suitable bearings 26 with which the car oriplatform 1 is provided and each of these rock shafts has a series of cranks 27 and isialso provided with a longer lever crank 28. Three of the cranks 27 are here shown on each shaft at points above and hetweeri the railway track rails and cach shaft alsothas one of said cranks 27 near each end andai:

22', the said points on the outer sides of the track rails. i

Each rock shaft operates a gang of shovels or temps 29 each of which has an operating rod 30, the said rods having their upper ends connected to bearing yokes 81k and the said bearing yokes beingr mounted on the wrists of the cranks 27. rThe rods 30 of the ramps or shovelspass through and are movable in openings 32 iu suitable guide frames orv supports 33, each of which is provided at suitable points with a pair of supporting rack arms 34.' The said guide frames 33 -arc arranged at opposite sides of the frame 9 and their respective rack arms 34 engage the upper and lower sides of openings 35 on a shaft 3G which is mounted in hearings in the frame 9 and the front. end of which is provided vwith a hand crank 37 whereby it may be revolved. The said rack arms 3ft also pass through suitable guides 38v with which the frame 9 provided. An operating yoke 39 is mounted for vertical reciprocating movementI above` lower end.v The wrists of thellever'cranksA 28 have their bearings and are movable in `the said slots 42, the lever cranks of the rock shafts 25 being thereby 'connected' to the said operating yoke.

j The pulley 12 has a crank pinr43 to which -is pivotally connected thel upper end 'of a pitman 44, the lower end of the latter being pivotally connected to the center of the operating yoke.

when the pulley 12 is driven by the motor 4, its crank pin and the pitman 44 impart 'vertical reciprocating motion to the yoke 39, that said yoke throughy the instrumentality of the lever cranks 28 causesth .crank shafts 25 to rock and, hence, the cran s 27 of said shafts alternately raise the tamps or shovels drive said tamps or shovels. ldownwardly, thus causing the tamps or shovels to operate on the roadbed, between the ties.

The gangs of tamps or shovels may be adjusted toward each other according to the width of the ties and for operation on the roadbed in the space bet-Ween the ties by properly turning the shaft 36 so as to cause its openings 35 by co-action with the rock arms 34 to move the guiding frames 33 of the tamps or Shovels toward and from each other, as will be understood.

Byy lowering the frame, the standard 10 which carries the operating pulley 12, the

said pulley andJ hence, also the operating yoke 39 will be lowered, thus causing the said yoke to turn the lever cranks 28 of 'the rock shafts 25 downwardly and raise the cranks 29 of said rock' shafts and hencecause the `tamps or shovels to be drawn upwardly by 'said cranks 28 to a sufficient height above the railway track and thus permit the car to be moved from point to point The depth at which the shovels or tamps operate may be controlled by thus raising' or lowering the standard l0 by means of the traveling nut 19, the screws 16 and the coasting devices hercinbefore described.

I have herein shown an electric motor for operating my improved tampin: machine but I would have it understood that the nio-tor may be of any type as, for instance, it may be a steam engineer an internal corn-l bustion motor as may be kdesired when the tamp is for use on steam or other railways not provided with electric current.

It will be understood that WhileI have herein'shown and described 'a preferred form of the invention, .I would havel it understoodthat changes may be made in the form, 4proportion and construction of the yseveral parts without departing' from 'the spirit of the invention and within the scope of the claims.
